What is a significant indirect benefit of building muscle through strength training exercises?

It helps improve how the body processes sugars and fats.

Although strength training might not seem immediately tied to cardiovascular output in the same way aerobic exercise does, it provides substantial indirect advantages critical for long-term heart support. Muscle tissue possesses a high metabolic activity level, meaning it actively consumes resources even at rest. By increasing muscle mass through resistance exercises, the body becomes more proficient at processing circulating sugars and fats. This improved metabolic function is key to achieving and maintaining a healthy body weight and significantly enhances the body's sensitivity to insulin, both of which reduce overall strain factors contributing to heart disease.
